A study examined the link between sodium intake and blood pressure in children and adolescents
between the ages of 8 and 18. The mean systolic blood pressure (SBP) was 112.8 mm Hg among
the 636 study participants who were overweight or obese and consumed high levels of sodium,
resulting in a 95% confidence interval for this group of 110.7 to 114.9 mm Hg.
The numerical value of the margin of error for this confidence interval is mm Hg.

2.1 mmHg
Step-by-step explanation:
The confidence is given by:
Mean ± margin of error
Confidence interval = (110.7 ; 114.9)
Mean = 112.8
Lower boundary = 110.7
Taking the lower boundary :
Lower boundary = mean - margin of error
110.7 = 112.8 - margin of error
Margin of Error = 112.8 - 110.7
Margin of Error = 2.1
